Umgaqo wokusebenza wempompo yamagnetic

Impompo yamagnetic yenziwe ngamacandelo amathathu: impompo, i-magnetic drive, kunye nemoto. Icandelo eliphambili le-magnetic drive liqukethe i-rotor yangaphandle yamagnetic, i-rotor yangaphakathi yamagnetic kunye ne-non-magnetic isolation sleeve. Xa i-motor iqhuba i-rotor yangaphandle yamagnetic ukuba ijikeleze, umhlaba wemagnethi unokungena kumsantsa womoya kunye nezinto ezingezizo ezemagneti, kwaye uqhube i-rotor yangaphakathi yamagnetic eqhagamshelwe kwi-impeller ukuze ijikelezise ngokuhambelanayo, ukuqonda ukuhanjiswa kwamandla okungaqhagamshelwanga, kunye nokuguqula okuguquguqukayo. itywina kwitywina elingatshintshiyo. Ngenxa yokuba i-shaft yepompo kunye ne-rotor yangaphakathi yamagnetic ivalwe ngokupheleleyo ngumzimba wempompo kunye nomkhono wokuzihlukanisa, ingxaki "yokubaleka, ukukhupha, ukuvuza, kunye nokuvuza" isonjululwe ngokupheleleyo, kunye nokuvuza kwemithombo yeendaba ezinokutsha, eziqhumayo, ezinobuthi kunye neziyingozi. imboni yokucoca kunye neekhemikhali ngokutywinwa kwempompo iyacinywa. Iingozi ezinokubakho zokhuseleko ziqinisekisa ngokufanelekileyo impilo yomzimba neyengqondo kunye nemveliso ekhuselekileyo yabasebenzi.

1. Umgaqo osebenzayo wempompo yamagnetic
Izibini ezi-N zemagnethi (n linani elilinganayo) zidityaniswe kwiirotha zemagnethi yangaphakathi nangaphandle ye-actuator magnetic ngolungiselelo oluqhelekileyo, ukuze iindawo zemagnethi zenze inkqubo yemagnethi edityanisiweyo epheleleyo kunye nenye. Xa iipali zemagnethi zangaphakathi nangaphandle zichasene enye kwenye, oko kukuthi, i-angle yokufuduka phakathi kweepali zemagneti ezimbini Φ=0, amandla omagnetic enkqubo yemagnethi awona aphantsi ngeli xesha; xa iipali zamagnetic zijikeleza kwipali enye, i-angle yokufuduka phakathi kweepali zemagneti ezimbini Φ=2π /n, amandla omagnetic enkqubo yamagnetic aphezulu ngeli xesha. Emva kokususa amandla angaphandle, ekubeni izibonda zemagneti zenkqubo yamagnetic zigxotha enye kwenye, amandla omagnetic aya kubuyisela umazibuthe kwelona gunya lisezantsi lamandla kazibuthe. Emva koko iimagnethi zihamba, ziqhuba i-rotor magnetic ukuba ijikeleze.

2. Iimpawu zesakhiwo
1. Umazibuthe osisigxina
Iimagnethi ezisisigxina ezenziwe ngezinto ezinqabileyo zomhlaba ezisisigxina ezinobushushu obubanzi (-45-400 ° C), ukunyanzeliswa okuphezulu, kunye ne-anisotropy efanelekileyo kwicala lemagnethi. I-demagnetization ayizukwenzeka xa iipali ezifanayo zisondele. Ngumthombo olungileyo wemagnethi.
2. Umkhono wokuzahlula
Xa kusetyenziswa umkhono wokwahlula wesinyithi, umkhono wokwahlula ukwindawo yemagnethi etshintshanayo ye-sinusoidal, kwaye i-eddy current idityaniswe kwicandelo lomnqamlezo ngokwe-perpendicular ukuya kwicala lomgca wamandla omagnetic kwaye iguqulwe ibe bubushushu. Inkcazo ye-eddy current yile: apho iPe-eddy current; K-njalo; Isantya esilinganiselwe ngu-n sempompo; T-magnetic transmission torque; F-uxinzelelo kwi-spacer; D-i-diameter yangaphakathi ye-spacer; resistivity of a material;-material Amandla okuqina. Xa impompo yenzelwe, i-n kunye ne-T inikezelwa ngeemeko zokusebenza. Ukunciphisa i-eddy yangoku kunokuqwalaselwa kuphela kwimiba ye-F, D, njalo njalo. Umkhono wokuzihlukanisa wenziwe ngezinto ezingezizo zetsimbi ezinokumelana okuphezulu kunye namandla aphezulu, okusebenza kakhulu ekunciphiseni i-eddy yangoku.

3. Ukulawulwa kokupholisa ukuhamba kwe-lubricant
Xa impompo yemagnethi isebenza, ulwelo oluncinci kufuneka lusetyenziswe ukuhlamba kunye nokupholisa indawo yesithuba se-annular phakathi kwerotha yangaphakathi yemagnethi kunye nomkhono owahlulayo kunye neperi yokukhuhlana kwebheringi etyibilikayo. Isantya sokuhamba kwesipholisi sikholisa ukuba yi-2% -3% yoyilo loyilo lompompo. Ummandla we-annulus phakathi kwe-rotor yangaphakathi yamagnetic kunye ne-sleeve yokuhlukanisa yenza ubushushu obuphezulu ngenxa ye-eddy currents. Xa i-lubricant yokupholisa ingonelanga okanye umngxuma wokugungxula ungagudi okanye uvalekile, ubushushu bendawo ephakathi buya kuba phezulu kunobushushu obusebenzayo bemagnethi esisigxina, kwaye i-rotor yangaphakathi yamagnetic iya kulahleka kancinci kancinci kwaye i-magnetic drive iya kusilela. Xa i-medium inamanzi okanye i-liquid-based based liquid, ukunyuka kweqondo lokushisa kwindawo ye-annulus kunokugcinwa kwi-3-5 ° C; xa i-medium i-hydrocarbon okanye i-oyile, ukunyuka kweqondo lokushisa kwindawo ye-annulus kunokugcinwa kwi-5-8 ° C.

4. Ukutyibilika
Izinto eziphathekayo ze-sliding bearings zeempompo zamagnetic zifakwe igraphite, zizaliswe nge-polytetrafluoroethylene, ii-ceramics zobunjineli kunye nokunye. Ngenxa yokuba iiseramics zobunjineli zinokuxhathisa ubushushu obulungileyo, ukuxhathisa umhlwa, kunye nokumelana nokukhuhlana, iibheringi ezityibilikayo zeempompo zemagnethi zenziwe ngeeseramikhi zobunjineli. Ngenxa yokuba iiseramics zobunjineli zibuthathaka kakhulu kwaye zine-coefficient encinci yokwandisa, ukukhutshwa kokukhutshwa akufuneki kube kuncinci kakhulu ukunqanda iingozi ezijingayo kwishaft.
Ekubeni i-sliding bearing yepompo yamagnetic ifakwe i-lubricated medium, izixhobo ezahlukeneyo kufuneka zisetyenziswe ukwenza iibheringi ngokweendaba ezahlukeneyo kunye neemeko zokusebenza.

5. Amanyathelo okukhusela
Xa inxalenye eqhutywayo ye-magnetic drive iqhuba phantsi komthwalo ogqithisiweyo okanye i-rotor ibambekile, iindawo eziphambili kunye neziqhutywayo ze-magnetic drive ziya kuzikhupha ngokuzenzekelayo ukukhusela impompo. Ngeli xesha, umazibuthe osisigxina kwi-activator magnetic uya kuvelisa ilahleko ye-eddy kunye nokulahleka kwemagnethi phantsi kwesenzo sokutshintshana kwemagnethi yerotor esebenzayo, eya kubangela ukuba ubushushu bemagnethi esisigxina bunyuke kunye ne-activator magnetic ukuba ityibilike kwaye isilele. .
Isithathu, iingenelo zempompo yamagnetic
Xa kuthelekiswa neempompo ze-centrifugal ezisebenzisa izitywini zoomatshini okanye ukupakisha ukupakisha, iimpompo zamagnetic zineenzuzo ezilandelayo.
1. I-shaft yepompo iyatshintsha ukusuka kwisitywina esiguqukayo ukuya kwisitywina esivaliweyo esivaliweyo, ukuphepha ngokupheleleyo ukuvuza okuphakathi.
2. Akukho mfuneko yokuthambisa ngokuzimeleyo kunye namanzi okupholisa, okunciphisa ukusetyenziswa kwamandla.
3. Ukusuka kwi-coupling transmission ukuya kwi-synchronous drag, akukho qhagamshelwano kunye nokukhuhlana. Inokusetyenziswa kwamandla aphantsi, ukusebenza kakuhle okuphezulu, kwaye inokunciphisa kunye nokunciphisa i-vibration effect, enciphisa impembelelo ye-motor vibration kwipompo yamagnetic kunye nefuthe kwi-motor xa impompo isenzeka i-cavitation vibration.
4. Xa ilayishwe kakhulu, i-rotors yangaphakathi nangaphandle yamagnetic ityibilika, ekhusela i-motor kunye nempompo.
Okwesine, amanyathelo okhuseleko
1. Thintela amasuntswana angangeni
1
(2) Emva kokuthutha indlela ekulula ukuyiqaqambisa okanye ukuyicombulula, yigungxule kwangethuba (galela amanzi acocekileyo kumngxuma wempompo emva kokumisa impompo, kwaye uyikhuphe emva komzuzu o-1 wokusebenza) ukuqinisekisa ubomi benkonzo yebherethi yesilayidi. .
(3) Xa uthutha i-medium equkethe amaqhekeza aqinileyo, kufuneka ihluzwe kwindawo yokungena kumbhobho wokuhamba kwempompo.
2. Thintela demagnetization
(1) Itorque yempompo yamagnetic ayinakuyilwa encinci kakhulu.
(2) Kufuneka iqhutywe phantsi kweemeko zokushisa ezichaziweyo, kwaye iqondo lokushisa eliphakathi lithintelwe ngokungqongqo ukuba ligqithise umgangatho. I-sensor ye-platinamu yokumelana nokushisa ingafakwa kwindawo yangaphandle ye-sleeve ye-magnetic pump isolation ukuze ibone ukunyuka kweqondo lokushisa kwindawo ye-annulus, ukwenzela ukuba i-alamu okanye ivale xa izinga lokushisa lidlula umda.
3. Thintela ukukhuhlana okomileyo
(1) Idling ithintelwe ngokungqongqo.
(2) Akuvumelekanga ngokungqongqo ukukhupha i-medium.
(3) Xa ivalve yokuphuma ivaliwe, impompo akufuneki iqhube ngokuqhubekayo ngaphezu kwemizuzu emi-2 ukunqanda i-actuator magnetic ekutshiseni ngokugqithisileyo kunye nokusilela.
